Definitions

• the present invention relates to pointing devices for controlling cursors on displays for personal computers and workstations and laptop computers and the like, and more particularly to devices and methods for translating the position of a computer mouse by finger movements .
• the most common form of pointing devices for personal computers and workstations is the electronic mouse.
• Touch pads and pointer sticks because of their compact nature, are the most commonly integrated pointing devices for laptop computers. Most laptop computers also permit an external mouse to be used with the laptop.
• the most common form of electronic mouse uses a rubberized ball on the underside of the mouse. Translation of the mouse causes the rubberized ball to roll. The rubberized ball is in contact with a pair of encoder shafts. Rolling motion of the rubberized ball in turn causes the encoder shafts to rotate. The rotation of the encoder shafts, and wheels associated therewith, generates a quadrature signal by the use of two pairs of LED's and photodetectors . This electronic signal is representative of the translation of the position of the mouse.
• the mouse In operation, the mouse is grasped with the hand, and movement of the mouse is effected by wrist motion and/or arm motion.
• the index and middle fingers are poised over actuator buttons, which can vary from one to three buttons and are generally located over the upper distal surface of the mouse.
• Prolonged use of the typical electronic mouse necessarily requires prolonged activation of muscles controlling the wrist and arm. It is well known that such prolonged use of the arm and wrist can result in a repetitive stress injury such as carpal tunnel syndrome.
• the electronic mouse is preferably used on a mouse pad which is essentially an 8.5 inch by 8.5 inch rubberized mat.
• the texture on the upper surface of the mouse pad provides traction for the rubberized ball.
• the size of the mouse pad accommodates the travel of the electronic mouse such that, in moving the cursor from one edge of the display screen to the opposite edge, the rubberized ball of the electronic mouse does not move beyond the edges of the mouse pad.
• laptop computers now have computing power and display screens comparable to desktop personal computers. More and more, laptop computers are being used as desktop computer replacements. The laptop computers generally have a smaller footprint than desktop personal computers. Many users who use laptop computers as desktop computer replacements prefer to use an externally attached electronic mouse as a pointing device.
• the pointer stick requires an external button to activate a selection after positioning the cursor at a desired location on the display screen.
• To click the selection button the user either has to re-position their digit (usually the index finger) over the selection button or use another digit (such as the thumb) to click the selection button.
• Many users find this secondary maneuver to be cumbersome.
• the touch pad also suffers from similar disadvantages when making a selection. More particularly, with the touch pad, movement of the cursor is controlled by movement of the tip of a finger over the surface of the touch pad. When a de-sired location of the cursor is reached, to make a selection, the user has to make a distinct tap on the surface of the touch pad, i.e., by lifting the finger off the surface of the touch pad and then hitting the surface of the touch pad with the tip of the finger. Because there is no distinct mechanical clicking associated with the act of selection, the user is not provided with an immediate sensory feedback to signal a successful selection. Touch pads are also typically provided with external selection buttons, but these are associated with the same disadvantages previously described for the pointer stick.
• a typical electronic mouse because of its size and long cable, does not allow for easy storage, e.g., with a mobile laptop computer.
• the present invention substantially overcomes the foregoing limitations of typical prior art electronic pointing devices by providing an electronic mouse in which the pointing and selection functions can be controlled by a single finger. Thus, the risk of repetitive stress injury is minimized by avoiding the constant wrist and arm movements used to control the movements of a conventional mouse.
• the present invention can be implemented with a optomechanical mouse or with an optical mouse.
• an object of the present invention to provide a pointing device controlled substantially by finger movement.
• Another object of the present invention is to provide an electronic mouse that can operate over a mouse pad with a small footprint. It is yet another object of the present invention to provide an electronic mouse that allows for easy storage and deployment.
• the present invention substantially overcomes the foregoing limitations of typical prior art electronic pointing devices by providing an electronic mouse controlled substantially by finger movement.
• the translation of the mouse can be controlled by the index finger placed over the primary selection button.
• Means for facilitating translation of the position of the mouse are provided for in the primary selection button.
• Means for facilitating translation of the position of the mouse include, but are not limited to, concave depressions, protrusions, and surface texture having a high coefficient of friction.

• FIG. 1 A preferred embodiment of the present invention is shown in Fig 1. More particularly, there is shown an electronic mouse 100 which comprises a housing 105 for containing the mechanical and electronic components (not shown) of the mouse, which mechanical and electronic components are of the sort well known in the art. Housing 105 can be circular or oval in shape, or any other shape that is considered to be ergonomically suitable.
• the side walls 110 of mouse 100 are inclined inwards, from the bottom 115 to the top 120, so as to define a circumferential groove 122 which is adapted to accommodate the thumb and fingers of a user.
• a primary button 125 is centrally located on the upper surface of the mouse. This primary button 125 is preferably substantially equivalent to the "left" button of a typical electronic mouse.
• One construction of this embodiment of mouse may include a rubberized ball (not shown) located on the bottom 115 of the mouse, directly below the primary button 125.
• An alternate embodiment may employ an electrical pickup (not shown) , which detects movement of the mouse relative to an accompanying pad.
• Another embodiment may employ an optical motion detector component which detects movement of the mouse relative to any visually-discernible surface.
• a second button 130 and a third button 135 are preferably disposed in the periphery of housing 105, preferably at the distal end (i.e., the forward end) 140 of housing 105, to the right and left of the primary button 125, respectively.
• the second and third buttons 130, 135, function similar to the "right” and “middle” buttons of a typical three-button electronic mouse.
• a scrolling wheel 145, for activating scrolling, is preferably located between the second and third buttons, 130, 135, distally (i.e., forwardly) of the primary button 125.
• Mouse pad 150 may be made of materials well known in the art so as to provide traction for a rubberized ball.
• typical operation of the present mouse involves clasping the mouse 100 between the user's thumb T and middle finger M of the user's right hand H.
• This embodiment is described in terms of right-handed operations, it is also possible to accommodate left-handed operations as well.
• the thumb T and middle finger M fit into the conforming groove 122 in the wall 110 of the housing 105.
• the groove 122 also prevents the mouse 100 from slipping off thumb T and middle finger M when the mouse is picked up.
• the tip P of the index finger F is positioned in the depression 155 of primary button 125.
• the invention provides two ways to control the movement of mouse 100, and thus the movement of an associated cursor (not shown) on a computer display screen (also not shown) .
• mouse movement is controlled with the user's thumb T and middle finger M, in the manner shown in Figs. 2 and 3. Movement of mouse 100 in the y direction (i.e., distally and proximally) is controlled by flexing and extending thumb T and middle finger M simultaneously while grasping mouse 100. Flexing thumb T and middle finger M pulls mouse 100 toward the user, translating mouse 100 in the negative y direction (i.e., proximally) and causing corresponding cursor movement. Extending thumb T and middle finger M pushes the mouse away from the user, translating the position of mouse 100 in the positive y direction (i.e., distally) and causing corresponding cursor movement.
• mouse 100 To move mouse 100 in the positive x direction (i.e., laterally to the right) so as to cause corresponding cursor movement, mouse 100 is pushed to the right with thumb T. To move mouse 100 in the negative x direction (i.e., laterally to the left) so as to cause corresponding cursor movement, mouse 100 is pushed to the left with the middle finger M.
• the user may bend the user's wrist W to the right and left while holding onto mouse 100 with thumb T and middle finger M.
• mouse 100 is moved with a sweeping motion while holding the mouse with thumb T and middle finger M.
• thumb T and middle finger M For example, to move the cursor from the bottom of the display screen to the top of the display screen, first, the user fully extends the user' s thumb T and middle finger M, translating the mouse 100 distally, which in turn causes the cursor to move part way up the display screen. Next, the user lifts mouse 100 up off mouse pad 150 and flexes their thumb T and middle finger M, while mouse 100 is off the mouse pad 150, so as to bring mouse 100 back to its initial position on mouse pad 150.
• the user With the mouse 100 sitting on the mouse pad 150, the user then extends their thumb T and middle finger M for additional translation of mouse 100, and hence corresponding cursor movement This sweeping motion is repeated until the cursor is close to the desired position. - The user may employ a similar sweeping maneuver to effect large cursor travel in the x direction.
• mouse 100 By grasping mouse 100 with thumb T and middle finger M, the mouse can be moved about as needed, with index finger F being used to activate buttons 125, 130 and 135 as appropriate.
• mouse 100 can be grasped with thumb T and ring finger R, leaving index finger F and middle finger M to activate buttons 125, 130 and 135 as appropriate.
• Another method of controlling cursor movement with mouse 100 is by dragging mouse 100 with index finger F positioned on the primary button 125, in the manner shown in Fig. 4.
• Mouse 100 can be dragged via the primary button 125, without actuating the primary button 125, by selecting a primary button microswitch (not shown) having a sufficiently stiff spring.
• the tip P of the index finger F may engage the sides of the depression 155 in the primary button 125 such that mouse 100 may be pushed frontwards and/or backwards and/or sideways without generation of sufficient vertical force to activate primary, button 125.
• Depression 155 also may include a small protrusion 160, best seen in Fig. 1, in primary button 125 that engages the inserted finger tip P. Traction between finger tip P and primary button 125 may also be increased with a material having a high coefficient of friction. Such materials are well known in the art.
• index finger F Small and fine cursor movements are best obtained by using index finger F to engage primary button 125 for mouse movement.
• Vertical cursor movement is preferably controlled by flexing and extending index finger F against the wall of depression 155, causing mouse 100 to move in the y direction.
• Horizontal cursor movement is preferably controlled by sideways movement of index finger F against the wall of depression 155, causing the mouse 100 to move in the x direction.
• the user may make a selection by "clicking", or depressing, primary button 125 with the same index finger F.
• a common cursor function is to drag an object or selected text by: (1) positioning the cursor on the desired object or text; (2) imparting sustained force on an appropriate button, e.g., the left button in a typical electronic mouse; (3) moving the mouse to a desired position; and (4) releasing the force on the button, thereby releasing the dragged object where the cursor is repositioned.
• an appropriate button e.g., the left button in a typical electronic mouse
• the present invention simplifies this operation.
• the user positions mouse 100 with index finger F such that the cursor is moved to a desired position on the screen.
• the user selects the object by clicking primary button 125. This is done by imparting a sufficient force on primary button 125 with the tip P of the user's index finger F.
• the user maintains force on primary button 125 with index finger F while, at the same time, moving mouse 100 with the same index finger F.
• the cursor may be roughly positioned with sweeping motions using thumb T and middle finger M as previously described.
• control of the cursor is effected by movement of mouse 100 using index finger F to engage primary button 125.
• Scrolling mechanism 145 can be located in front of, or behind, primary button 125.
• primary button 125 is located along a midline longitudinal axis.
• the ball is preferably located directly below primary button 125 so as to avoid any swiveling effect when mouse 100 is moved.
• Primary button 125 is preferably located near the center of the mouse's body.
• a modification of the present embodiment provides a primary button 125 located in the forward end 140 of mouse 100.
• -scrolling means 145 can be located behind primary button 125.
• a rear extension 200 which may be attached to the rear of mouse 100.
• Rear extension 200 is provided for those users who prefer a mouse with a larger bulk not unlike a conventional mouse.
• Rear extension 200 generally comprises a body 205 and a pair of forwardly-extending arms 210. Arms 210 are complementary to the mouse's circumferential groove 122, and extend beyond the equator of the mouse's housing 105, such that arms 210 can snap into groove 122 and thereby lock rear extension 200 to mouse 100.
• Rear extension 200 is preferably formed out of a tough, durable, light-weight plastic.
• rear extension 200 could be formed with a relatively flat upper rear surface 215, with or without additional input buttons (not shown) and/or an electronic input pad (also not shown) to permit pen entry of a signature or sketch.
• rear extension 200 includes such buttons or electronic input pad
• rear extension 200 must also be electrically connected to mouse 100 so that the signals from the buttons or electronic input pad can be transferred to the mouse and hence to the computer.
• Such an electrical connection can be achieved in ways well known in the art, e.g., by using simple male-female plug-in electrical connectors.
• buttons 300, 305 may be configured to activate the "backward” and “forward” buttons of a Web browser, so as to facilitate Web browsing actions using mouse 100.
• the electro-mechanical activation switch of primary button 125 is replaced by a pressure sensor wherein pressure on the primary button 125 by the finger F causes an electronic signal to be sent to the computer, and further wherein the amplitude of the electronic signal is a function of the magnitude of the pressure applied by the finger.
• This embodiment of the invention is particularly useful in graphic software, where the level of the digital pressure is translated as the thickness of a line drawn on the computer screen. In other words, a thicker line may be drawn by pressing harder on primary button 125, while moving mouse 100 at the same time, and a thinner line may be drawn by reducing the pressure on primary button 125.
• the left button 130 and the right button 135 can be programmed to correspond to the left and right buttons of a conventional electronic mouse.
• the scrolling wheel 145 instead of scrolling a computer display to unobserved portions of the computer display, can be programmed to move the cursor on the computer display in the third axis as may be the case in three dimensional graphics representation. Yet another use of the scrolling wheel 145 is to program it to act a continuous zoom function either by itself or in combination with any one of the control keys on the keyboard.
